What are the ordered pairs for y=1/3x+4 , y=2x-1?

1 Answer

May 8, 2016

$(x, y) = (3, 5)$ $(x,y)=(3,5)$

Explanation:

If $XXX y = \frac{1}{3} x + 4$ $color(white)("XXX")y=1/3x+4$
and $XX y = 2 x - 1$ $color(white)("XX")y=2x-1$
then
$XXX 2 x - 1 = \frac{1}{3} x + 4$ $color(white)("XXX")2x-1=1/3x+4$

$XXX \frac{5}{3} x = 5$ $color(white)("XXX")5/3x=5$

$XXX x = 1$ $color(white)("XXX")x=1$
$XXXXXXX$ $color(white)("XXXXXXX")$ and substituting this $\to y = \frac{1}{3} x + 4$ $rarr y=1/3x+4$

$XXXXXXXXXXXXXXXXXXXX$ $color(white)("XXXXXXXXXXXXXXXXXXXX")$ gives $y = 5$ $y=5$
